Forms :: Multiple Forms Open And Close

Apr 16, 2009

I have two forms frmMain and frmNew, and one module modMain. In modMain I hold public variables which are needed for application. My question is how to open and close those two forms when needed? I ask this because if i set frmMain as startup form, then when closed, application will end, and one of those two forms will always be displayed. Also if I set frmNew as startup form, then when I close this form, application will also end. Is there a way to do this from module or something so my application won't end after closing and opening any of those two forms?

Open And Close Multiple Forms?

Apr 24, 2009

I have an application that has multiple forms. The "main" form within this application can be accessed from other forms. However, each time this "main" form is accessed throughout the application, a "new" instance is created, resulting in multiple instances of this form being open.

I would like to have "only" one instance of this form open at one time. If it is currently opened, I would like it to be brought to the forefront, instead of opening a new instance.

Multiple Forms Program Needs To Open Successive Forms Somehow?

Nov 3, 2009

i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?

Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.

What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.

Close() Puts Forms Into Crazy Open/Close Loop?

Mar 4, 2011

In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another

VS 2008 : Get 2 Forms To Close At Different Times Using A Timer On Each Of The 2 Forms?

Apr 21, 2010

i have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.

This is my form layout:

Quote:
frmMain
Frm1
Frm2

Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...

Click on the first button (showing the Frm1 form)

wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.

Application That Has Multiple Front Ends Developed Using Windows Forms / WPF / ASP / Compact Framework Mobile Forms

Apr 9, 2010

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.

Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

May 25, 2010

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.

How can I get it to fire the form1 sub routine on the close event of form2

Forms :: Maintaining Multiple Forms Positioning?

Jul 26, 2010

Launch a dialogue window from the main form, and then another dialogue window from that dialogue window. If you close the second dialogue window and call dispose the main form vanishes under any other open windows. This doesn't happen by closing a dialogue window normally, but I am attempting (rightly or wrongly) to stop memory useage creeping up by disposing of it.

So, the question is - what method can be employed to maintain the position of the windows?

Forms :: Retaining Data Across Multiple Forms

Sep 8, 2010

VB.NET newbie here... I have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out... and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

Forms :: When Me.close() Doesn't Close Form

Mar 2, 2009

I have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.

Private Sub cmdNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNext.Click
Dim f As New frmOrder3

.net - Parent/Child Relationships Failing When Getting Data From Parent Class With Multiple Forms Open?

Jun 24, 2009

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.

dim l = Mainform.subform.listofdata

Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this

Protected Friend frmMain as Mainform
frmmain = new mainform

In frmMain I am doing this

Protected Friend frmsub as new Subform'

.net - Given A Large Number Of Objects, Create Multiple Forms In Designer For Them Or Use Code To Create The Forms?

Dec 29, 2010

If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.

#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

Forms :: Forms To Open As Part Of A "bigger" Program?

Mar 2, 2010

I would like my forms to open as part of a "bigger" program, where there is a screen that fills the monitor and inside this screen is my form, centered. When a new form is opened, only the new form will be displayed...it will not be form on top of form.It would look similar to the screen in the following link, except the form inside the bigger screen would not have the minimize, maximize, or close buttons.I am just wondering if there is a property in VB.NET forms that will allow this to happen.
